Configuring Ipv6 Multicast Source Port Filtering; Enabling Dropping Unknown Ipv6 Multicast Data - HP 5920 series Configuration Manual

Configuring IPv6 multicast source port filtering

When the IPv6 multicast source port filtering feature is enabled, the port can only connect to IPv6
multicast receivers rather than multicast sources. The port denies all IPv6 multicast data packets but it
permits multicast protocol packets.
If this feature is disabled, the port can connect to both multicast sources and IPv6 multicast receivers.
You can enable multicast source port filtering either for the specified ports in MLD-snooping view or for
the current port in interface view. The two configurations have the same configuration priority.
Configuring IPv6 multicast source port filtering globally
Step
1. Enter system view.
2. Enter MLD-snooping view.
3. Enable IPv6 multicast source
port filtering.
Configuring IPv6 multicast source port filtering on a port
Step
1. Enter system view.
2. Enter Ethernet interface view.
3. Enable IPv6 multicast source
port filtering.

Enabling dropping unknown IPv6 multicast data

Unknown IPv6 multicast data refers to IPv6 multicast data for which no forwarding entries exist in the MLD
snooping forwarding table. When the switch receives such multicast data on a port, one of the following
occurs:
When the function of dropping unknown IPv6 multicast data is disabled, the switch floods unknown
•
IPv6 multicast data in the VLAN that the data belongs to, causing network bandwidth waste and
low forwarding efficiency.
• When the function of dropping unknown IPv6 multicast data is enabled, the switch forwards
unknown IPv6 multicast data to other router ports instead of flooding it in the VLAN. If no other
router ports exist, the switch drops the unknown IPv6 multicast data.
To enable dropping unknown IPv6 multicast data for a VLAN:
Step
1. Enter system view.
2. Enter VLAN view.
